BATTERY CABLE CONNECTOR Filed Aug. 16, 1939 15 V6 70R 1776, E0601? WE/VG'ER Patented Nov. 19, 1940 UNITED STATES PATENT OFFICE Application August 16, 1939, Serial N: 290,419 In Canada April 19, 1938 1 Claim.

My invention relates to a battery cable connector.

The objects of the invention, generally, are to improve on known battery cable connectors.

A specific object of the invention is to provide a battery cable connector which can be quickly and securely locked to the battery post, and easily and quickly removed, without damaging either connector or battery post.

Another; specific object of the invention is to make such a device to a simple yet sturdy construction, thus providing an inexpensive yet efficient connector.

Other objects and advantages of my connector may be gleaned upon perusing the specification to follow, in the light of the drawing.

In the drawing, wherein like numerals of reference indicate corresponding parts in the var ous figures.

20 Figure 1 is a side elevation of my device, locked in operative position upon a battery post.

Figure 2 is a plan view of Figure 1. Figure 3 is a fragmentary cross section of Figure 1.

25 Figure 4 is a top plan view of the locking wedge or cam.

Figure 5 is a cross section of Figure 4.

Figure 6 is a side elevation of the cam or wedge actuating member.

30 Referring now by numerals to the drawing, P indicates a battery post of a typical battery, such as is used on motor vehicles, and D indicates the device or battery cable connector complete, shown in Figure 1 as locked in operative position upon 35 the post. The battery post is tapered as usual.

I0 is the body portion of the device, in the form of a sleeve, tapered on its inside face or otherwise adapted to be fitted onto the battery post P into electrical engagement therewith.

40 Extending from one side of the sleeve [0 is a cup-like member ll forming a socket adapted to receive one end of the battery cable C, and in which the cable is suitably soldered as usual. Preferably, as shown, the socket member is ar- 45 ranged with its axis in a plane at right angles tothe axis of the battery post P. Preferably, also, the inside face of the socket member is provided with, say, three grooves l5. Extending laterally and horizontally from the sleeve II] are 50 two spaced lugs I 6, these lugs being provided with aligned circular holes or apertures H. The lugs are preferably disposed substantially diagonally opposite the socket member II. The wall of the sleeve is apertured or slotted between the two 55 lugs 16, as at l8, to expose the battery post to a locking wedge or cam I9 which is mounted between the two lugs. The wedge is adapted to be moved toward the post, to engage the same, and to be moved away from the post, to disengage the same. The device is thus locked to the post by the wedging or camming action of the wedge l9, or, in other words, the battery post is bound 5 or pinched between the wedge and the inside wall of the sleeve.

The wedge is moved laterally between the lugs It, to either engage the post or disengage the same, by turning a bolt or member 22 journalled 10 in the apertures I1 and formed with an eccentric means 23 turning in a circular aperture 25 formed in the wedge. The bolt or member 22 is conveniently formed with a square head 21.

The inside face of the sleeve is preferably 15 formed with vertically directed fins or ridges 28 which are adapted to bite into the battery post when the locking wedge is pressed against the post. Preferably also, the post-engaging face of the wedge is formed with, say, two spaced horizontally directed fins or ridges 29, also adapted to bite into the post when the wedge is pressed against the post.

It will be seen that the bolt or member 22 turns on an axis parallel with the axis of the battery post, and has its operating head 21 above the top of the sleeve, and therefore, above, or substantially above, the top of the battery post when the device is in operative position. The task of binding or looking the device upon the post, or of 30 releasing the device from the post, is greatly facilitated.

The use of fins on the wedge and on the sleeve, operates to better bind or secure the device in operative position, and without appreciably damaging, if at all, the battery post.

I claim:

A battery cable connector comprising a sleeve adapted to fit onto the battery post, a socket from said sleeve adapted to receive one end of a cable, a pair of spaced lugs extending from said sleeve and disposed in planes substantially at right angles to the axis of said sleeve, said sleeve having a slot extending between said lugs, a member bodily slidable between said lugs and through said slot to engage and disengage the battery post, said member having its post engaging face curved to partly embrace the post, and a spindle journalled in said lugs to turn on an axis substantially parallel with the axis of said sleeve and having means rigid with one end thereof for turning said spindle, said spindle having rigid therewith an eccentric turning in said member for sliding the same between said lugs.
